An anime and manga convention is a fan convention with a primary focus on anime, manga and Japanese culture. Anime conventions are commonly multi-day events hosted at convention centers, hotels or college campuses. They feature a wide variety of activities and panels, with a larger number of attendees participating in cosplay than most other types of fan conventions. Anime conventions are also used as a vehicle for industry, in which studios, distributors, and publishers represent their anime related releases. They also take place in multiple different countries, such as Japan, South Korea, China, India, Indonesia, the United States, Canada, Brazil, Australia, New Zealand, the United Kingdom, Ireland, France, Germany, Italy and Spain.
